DETAILED DESCRIPTION

The various concepts introduced above and discussed in greater detail below may be implemented in any of numerous ways, as the described concepts are not limited to any particular manner of implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

FIG. 1 is a block diagram of a computer system 100 including a network 101, a first client 102, a second client 106, and a server 104. The system 100 may use at least one computer network 101. The network 101 may include a local area network (LAN), wide area network (WAN), a telephone network, such as the Public Switched Telephone Network (PSTN), a wireless link, an intranet, the Internet, or combinations thereof. The network 101 may connect one or more devices via an Open Systems Interconnection (OSI) model. In some implementation, the network 101 may use an internet protocol suite, including the Transmission Control Protocol (TCP) and the Internet Protocol (IP).

The first client 102, the second client 106, and the server 104 may each be a computing device. A computing device (e.g. a data processing system) may include one or more processors, memory, and network interface. The one or more processors may be configured to execute instructions stored in memory to perform one or more operations described herein. The one or more processors and the memory device may form a processing module. The processor may include a microprocessor, a general purpose processor, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a data processor, a logic devices, a central processing unit (CPU), a graphics processing unit (GPU), a group of processing components, other suitable electronic processing components, or combinations thereof. The processor may be connected directly or indirectly (e.g. via a bus) to the memory and the network interface. The memory may include, but is not limited to, any type of volatile, non-volatile memory, media, memory device, electronic, optical, magnetic, semiconductor memory device, or any other storage or transmission device capable of providing processor with program instructions and/or data. The memory may include an optical disk, magnetic disk, hard disks, internal disks, removable disks, magneto-optical disks, memory chip, read-only memory (ROM), random-access memory (RAM), Electrically Erasable Programmable Read-Only Memory (EEPROM), erasable programmable read only memory (EPROM), flash memory, or any other suitable memory from which processor can read instructions and/or data. The instructions may include code and/or data from any suitable machine-readable code or source code. The machine code may be from source code, which may be in one or more computer programming languages (including scripting language or markup language) such as, but not limited to, ACTIONSCRIPT®, C, C++, C#, Cascading Style Sheets (CSS), DART®, ECMASCRIPT®, Extensible Markup Language (XML), JAVA®, JAVASCRIPT® including JAVASCRIPT® Object Notation (JSON), PERL®, Hyptertext Markup Language (HTML), PYTHON®, TypeScript, VBScript, VISUAL BASIC®, or any other language. In addition to the processing circuit, a computing device may include one or more databases configured to store data. A data storage device may be connected to a computing device through the network 101. The computing device may include input and/or output (e.g., an electronic display, a touch screen, a virtual reality display, a speaker, a keyboard, a pointing device, a mouse, a microphone, a printer, a gamepad, a camera, etc.). The computing device may be connected to the network 101 via a network interface. The network interface may be a communication interface that includes wired or wireless interfaces (e.g., jacks, antennas, transmitters, receivers, transceivers, wire terminals, Ethernet ports, WiFi transceivers, Bluetooth, Bluetooth Low Energy, near field communication (NFC), ultrasonic sounds, radio-frequency identification (RFID), etc.) for conducting data communications with local or remote devices or systems via the network 101. A network interface may have a corresponding module or software that works in conjunction with hardware components. The network interface may allow a computing device to communicate with and exchange data with other computing devices via the network 101. The network interface may receive data from or transmit data to the processor, memory, and/or any module or application in memory.

The first client 102 may be a computing device. Some implementations of the computer system 100 may include a plurality of first clients 102. The first client 102 may include any number and/or type of user-operable electronic device. For instance, a first client 102 may include a desktop computer, laptop, convertible PC, smartphone, wearable device, smart watch, tablet, phablet, personal digital assistant, set-top box, smart television, gaming console device, mobile communication device, remote workstation, client terminal, entertainment console, or any other device configured to communicate with other computing devices, systems, and servers via the network 101. The first client 102 may be capable of communicating with the server 104, and/or the second client 106 via the network 101. The first client 102 may be capable of determining its location, such as geographic location (“geolocation”). In some implementations, the first client 102 may determine its geographic location via global positioning system (GPS). In some implementations, the first client 102 may determine its geographic location via connection with a network 101. For instance, the first client 102 may be assigned an IP address by the network 101 and determine its geolocation via the IP address. In some implementations, the first client 102 may be capable of receiving location information from user input. For instance, a user may select a location on a map or designate coordinates. In some implementations, the location may be defined in terms of the network location or characteristics. For instance, the location of the first client 102 may be defined in terms of the IP address, ping or number of hops to a specified IP address, access to a specific network, type of network, etc.

The first client 102 can execute an application to send content to a server 104 over the network 101. An application may be a mobile application, a web browser, a chat program, a stand-alone application, a widget application, a plug-in application, or any type application. The widget and the plug-in application may be a third-party application. The application may be written in any programming language. For instance, the widget or the plug-in application may be written in JAVASCRIPT. The application may use an application programmable interface (API) to communicate to the server 104 or an API to communicate with a second application executing on the first client 102 configured to communicate with the server 104. The application may be configured to allow a user to select a content to be shared, and accept a unique identifier from the user. The application may also receive location input from the user, or use a location of the first client 102. The application on the first client 102 may send the shared content, unique identifier, and the location to the server 104. The shared content, unique identifier, and the location are described in greater detail below in relation to FIG. 4. In some implementations, the first client 102 may send the unique identifier to the second client 106 via the network 101 and/or via the network interface. For instance, the first client 102 may send the unique identifier to the second client 106 via a Bluetooth signal, NFC, or ultrasonic sound. In another instance, a first user of the first client 102 may communicate the unique identifier to a second user of the second client 106. For instance, the first user may tell the second user the unique identifier via email, short message service (SMS) text, instant messaging, speech, etc. In some implementations, the first user may update a website or a social networking site (e.g. via TWITTER) the unique identifier, through which the second user may obtain the unique identifier.

The second client 106 may be a computing device, similar to the first client 102. Some implementations of the computer system 100 may include a plurality of second clients 106. A plurality of second clients 106 may request the same shared content. A second client 106 may receive input from a user of the second client 106. The second client 106 may be configured to request the shared content from the server 104. In some implementations, the second client 106 may receive a notification from the server 104 without sending a request to the server 106. The notification may indicate, for instance, an availability of a shared content. In some implementations, the second client 106 may execute an application that communicates with the server 104 that downloads the shared content.

The server 104 may be a computing device. Some implementations of the computer system 100 may include a plurality of servers 104. A server 104 may be connected to the network 101 and be configured to communicate to a first client 102 and a second client 106. The server 104 may comprise memory, processor, and network interface. The server 104 may further comprise a database or be configured to communicate with a database. The server 104 may be part of an infrastructure provider or a cloud computing platform. The server 104 may execute one or more virtual machines. The server 104 is described in greater detail in relation to FIG. 3.

FIG. 2A is a flow diagram depicting a method for sharing content from a first client to a second client. In brief overview, the method 200 generally includes: receiving a shared content, a first location, and a unique identifier (step 205); receiving a request from a second client, the request comprising a second location and the unique identifier (step 210); determining that the second location is within a predefined distance from the first location (step 215); and sending the shared content to the second client (step 220). The method optionally includes handling API calls associated with the shared content (step 208) and handling API calls of the request (step 212).

Still referring to FIG. 2A, and in more detail, the method includes receiving a shared content, a first location, and a unique identifier (step 205). A server may receive the shared content, first location and unique identifier. A first client may send the shared content, first location and unique identifier. The server may associate the first location and the unique identifier with the shared content.

The shared content may comprise one or more of file, calendar event, document, picture, video, audio, streaming media, rich media, and application data. In some implementations, the shared content may be specified by the first client and retrieved by the server via the network. For instance, the first client may specify the URL of the shared content and the server may download the shared content. In some implementations, the shared content may be hosted on a file sharing service and the server may download or copy the content from the file sharing service. In some implementations, the server may store a reference or the location of the content (e.g. the URL or on the file sharing service) instead of downloading or copying the content. The shared content may comprise an access to a stream of data from the first client 102; for instance, the shared content may enable a video stream and/or a voice-over-IP from the first client 102 to a second client 106. The shared content, first location and unique identifier are described in greater detail in relation to FIG. 4.

In some implementations, the server may determine whether the unique identifier is already in use. For instance, the server may receive a unique identifier, compare it against a plurality of unique identifiers in a database, and determine that the received unique identifier may not be used because it is in the plurality of unique identifiers. The server may then notify the first client for another unique identifier or suggest a generated unique identifier not in the plurality of unique identifiers. In some implementations, the server and/or the first client may generate a unique identifier. In some implementations, the first client may not send the unique identifier, and the server may generate or assign the unique identifier to the shared content. For instance, the unique identifier may be generated based on the first location. In some implementations, the first client may be logged in to an account before sending the shared content, and the server and/or the first client may generate or assign a unique identifier based on the account. The unique identifier may be generated based on one or more of the account, the shared content, the first location, the predefined distance, and/or configuration settings. For instance, the unique identifier may be generated via a hash function or a concatenation of the first location and an account name of the account. In another instance, a characteristic of the shared content, e.g. file name or file size, may be used as an input to a hash function that outputs a unique identifier. In some implementations, the unique identifier may be randomly generated. In some implementations, if the unique identifier is already in use, the server may generate a second unique identifier not in the plurality of unique identifier. In some implementations, the server may communicate with a database storing a plurality of unique identifiers and receive an available unique identifier not in the database. In some implementations, the server may filter the unique identifier, for instance for profanity or vulgar words. The filtered unique identifier may be presented to a first user of the first client or renamed. In some implementations, the server may filter or rename a received unique identifier based on availability in the database storing the plurality of unique identifiers.

In some implementations, a shared content may have the same unique identifier as one or more unique identifiers in the plurality of unique identifiers, such that the unique identifier may not be unique. In such implementations, a combination of the unique identifier and the first location may be unique as compared to all other combinations in the plurality of unique identifiers with the respective locations. For instance, the unique identifier may be “Interview Calendar Invite” with an associated first location in Atlanta, Ga. Another unique identifier in the plurality of unique identifiers may also be “Interview Calendar Invite” with an associated location of Boston, Mass. Both combinations of unique identifiers and locations may be allowed. In some implementations, a combination of the unique identifier and an account associated with the first location may be unique as compared to all other combinations in the plurality of unique identifiers with the respective accounts.

In some implementations, the first location may be a location of the first client, a location of an account associated with the first client, or a location specified on the first client. For instance, the first location may be determined by the first client which be a GPS-enable device. In another instance, the first client may be logged in under a first account associated with a first client. In yet another instance, a first user may specify the first location on a map presented on the first client. In yet another instance, an application or a plug-in executing on the first client may specify the first location. In some implementations, the first client may not send the first location, and the server may determine the first location of the first client. For instance, the server may determine a network characteristic of the first client (e.g. IP address) and determine the location of the first client. In some implementations, the first client may be logged in to an account before sending the shared content, and the server may determine a default location from the account; when the first client uploads the shared content, the server may associate the default location with the shared content. In some implementations, the server may obtain the first location by querying the first client. The first location may be defined in terms of geolocation, postal address, IP address, as part of a geographic hierarchy, etc.

In some implementations, the server may further receive a predefined distance from the first client or specified by an account associated with the first client. The predefined distance may define, delimit, or restrict the shared content within an area, a geographic region, or a location centered on the first location. In some implementations, the predefined distance may define a maximum distance between the first location and a second location. The predefined distance may be any distance between, for instance, zero feet to five hundred miles. In some implementations, the predefined distance may define a maximum distance between the first client and the second device. In some implementations, the server may not receive a predefined distance, and in such implementations, the server may associate a default predefined distance with the shared content. In some implementations, the predefined distance may be unlimited, such that the shared content may be accessed from anywhere. In some implementations, the predefined distance may be defined in terms of a geographic hierarchy. The predefined distance may be defined in terms of a zip code, phone number area code, city, county, state, country, or any other geographic designation. For instance, the predefined distance may specify that any requests for the shared content may be made from within the same zip code as the first location. In some implementations, the predefined distance may be defined in terms of network characteristic. For instance, the predefined distance may be defined in terms of range of IP addresses, geographic regions associated with IP addresses, pings or number of hops to a specified IP address or domain address, access to a specific network such as a specific service set identifier, type of network such as WiFi or cellular data connection, etc.

In some implementations, the server may receive additional configuration settings from the first client. For instance, the server may receive a configuration setting for whether the shared content should be broadcasted to one or more second clients within a predefined distance from the first location. In implementations where the server receives a broadcast setting for the shared content, the serve may identify one or more second clients to which the server will broadcast the availability of the shared content. For instance, the server may notify a plurality of second clients that are each determined to be within a predefined distance from the first location, as described in relation to step 215. In some implementations, each second client may be associated with an account and/or a setting that specifies that the second client may receive or view broadcasted shared content. In some implementations, each second client may be associated with the unique identifier, with a password associated with the shared content, or any other authorization or authentication. In some implementations, the server may determine the second location in response to the second client executing an application or a plug-in. After notifying the plurality of second clients, the server may receive from a second client a request for the shared content as described in relation to step 210.

In another instance, the server may receive a password for the shared content, such that any second client requesting the shared content with the unique identifier must also provide the password to access the shared content. In some implementations, one or more configuration settings may be used together. For instance, the broadcast setting may be combined with the password setting; a password may be required to be notified of a broadcast of the shared content and/or to access the shared content. In some implementations, the configuration setting may include additional authorization or authentication required for accessing the shared content. For instance, a second client must provide the additional authorization when attempting to access the shared content. The additional authorization or authentication may be used by an application or a plug-in executing on the first client and/or the second client. In some implementations, the configuration setting may include a valid time parameter, which may define a duration of time the shared content will be available to be accessed or a time at which the shared content will not be accessible. The duration of time may be any duration of time between, for instance, 30 seconds to indefinite (e.g. until the shared content is taken down by a first account associated with the shared content, until the first account is deactivated, or until the collapse of the universe). In some implementations, one or more of the configuration settings may be set with default values. For instance, the default value for the duration of time may be one year.

In some implementations, the server may optionally handle API calls associated with the shared content (step 208). The API calls may be part of the shared content or part of configuration settings. The API calls may include one or more parameters. For instance, a plug-in identifier may be a parameter of an API call. A plug-in may be associated with a plug-in identifier which may be passed in as a parameter of an API call. A plug-in may include, for instance, a chat program, or a pillow fight program, etc. In some implementations, the API call may include accessing a database, to modify or create a shared content. For instance, a pillow fight plug-in may make an API call that updates a document in a database that stores a time and location of a pillow fight event. In some implementations, an API call may generate a unique identifier such that the unique identifier comprises the plug-in identifier, shared content, and or the first location.

The server may receive a request from a second client, the request comprising a second location and the unique identifier (step 210). The server may determine that the unique identifier received from the second client is the same as the unique identifier received from the first client. In some implementations, the second location may be a location of the second client, a location of an account associated with the second client, or a location specified on the second client. For instance, the second location may be determined by the second client which may be a GPS-enabled device. The second location may be associated with the second client or with a second account logged in on the second client. The second location may be specified by a second user on the second client or by an application or a plug-in executing on the second client. In some implementations, the request may not specify a second location. The server may retrieve a default location associated with the second client or may process the request without a second location.

The second client may receive the unique identifier from the first client. The first client may send the unique identifier to the second client. In some implementations, the first client may send the unique identifier via a Bluetooth signal. For instance, the first client may pair with the second client via a Bluetooth connection. In another instance, the first client may transmit the unique identifier to the second client without pairing via a Bluetooth signal using advertising mode or friendly name. In some implementations, the second client may receive the unique identifier from the first client via NFC. In some implementations, the second client may scan for the unique identifier. For instance, the second client may scan a QR code and decode it for the unique identifier. In another instance, the second client may scan a RFID tag for the unique identifier. In some implementations, a first user of the first client may communicate the unique identifier to a second user of the second client. The second client may then use the unique identifier as part of a request to the server for the shared content.

In some implementations, the server may further receive a password. The server may receive the password separately (e.g. in a subsequent communication with the second client) or as part of the request comprising the unique identifier and the second location. The password may be required depending on whether a password was specified by the first client when uploading the shared content. The server may further receive additional authorization or authentication. For instance, a plug-in executing on the second client may be a chat program, and the chat program may send an authorization information specifying that the second client is authorized by the first client to communicate with the first client.

In some implementations, the server may check the unique identifier against a plurality of unique identifiers. The server may find one unique identifier from the plurality of unique identifiers that matches the unique identifier received from the second client. In some implementations, the server may access or query a database storing the plurality of unique identifiers. The server may access the database with the unique identifier or with a combination of the unique identifier and the second location. The database may return an entry in the database that comprises the shared content, the unique identifier, and the first location. In some implementations, the entry may further comprise the account associated with the first device and/or the shared content. In some implementations, the database may first look for the unique identifier received from the second client, and upon not finding the unique identifier, notify the server that no entry with the specified unique identifier exists. In some implementations, the database may find a plurality of entries, each entry matching the unique identifier received from the second client and each entry associated with a respective shared content. For instance, the unique identifier is “Interview Calendar Invite,” there may be multiple entries in the database, each comprising a unique identifier of “Interview Calendar Invite” and a respective shared content. One of the shared content may be for an interview in Atlanta, Ga., and another shared content may be for an interview in Boston, Mass. In some implementations, each of the plurality of entries may be considered as a match for the unique identifier. In some implementations, the server and/or the database may not find any unique identifiers in the plurality of unique identifiers that matches the unique identifier received from the second client. In such implementations, the server may notify the second client that the received unique identifier is invalid.

In some implementations, the server may determine that the unique identifier in the plurality of unique identifiers is associated with a shared content and a password. In such implementations, the server may determine whether the password provided by the second client matches the password associated with the shared content. If the passwords do not match, the server may inform the second client that the password provided by the second client was invalid. If the passwords match, the server may continue processing the request from the second client. In some implementation, the server may perform additional checks on authorization and authentication. For instance, the unique identifier found in the plurality of unique identifier may be associated with a shared content and additional authorization and/or authentication.

In some implementations, the server may optionally handle API calls associated with the request (step 212). The API calls may be part of the request. In some implementations, the API calls may be generated based on the unique identifier. For instance, part of the unique identifier may be a plug-in identifier. The API calls may include one or more parameters. For instance, a plug-in identifier may be a parameter of an API call. In some implementations, the API call may include accessing a database, to modify or access a shared content. For instance, a pillow fight plug-in may make an API call that access a document in a database that stores the time and location of a pillow fight event.

The server may determine that the second location is within a predefined distance from the first location (step 215). After finding a unique identifier that matches, the server may compare the first location associated with the found unique identifier with the second location of the response from the second client. The comparison of the first location and the second location may be a determination of a distance between the first location and the second location. The server may determine that the distance is within (or less than) a predefined distance. The distance may be determined as a geographical distance, for instance using a flat-surface formulae, spherical-surface formulae, or a ellipsoidal-surface formulae. The predefined distance may be a default value, defined by the first client, or associated with the shared content. In some implementations, the server may determine that the distance between the first location and the second location is greater than the predefined distance. In response, the server may inform the second client that the shared content is unavailable due to the distance being greater than the predefined distance. In some implementations, the server may compare the first location with the second location using a geographic hierarchy. For instance, the first location may specify a city, and the predefined distance may specify that the second location must be within the same city as the first location. In some implementations, the server may compare the first location with the second location using a network characteristic specified by the predefined distance. For instance, the predefined distance may specify a range of IP addresses and the server may determine whether the second client at the second location has an IP address that is within the range of IP addresses. In some implementations, matching passwords and performing additional authorization and authentication may occur after determining that second location is within a predefined distance from the first location.

In some implementations, the server may determine a plurality of distances for a plurality of entries that each match the unique identifier, and determine one or more entries from the plurality of entries that are within a predefined distance from the first location. For instance, the server may find a plurality of entries in the database, each entry comprising unique identifier of “Pillow Fight.” Each entry may be associated with a respective location. The server may compare the second location in the request with each respective location and determine one or more entries that are each within a predefined distance from the first location. The server may display the one or more entries, or the one or more shared content associated with the entries, to the second client.

In some implementations, the server may not determine that the second location is within a predefined distance from the first location. For instance, the server may determine that the predefined distance is not defined, a negative value, infinity, or some value indicating that the second location does not need to be within the predefined distance of the first location. In another instance, a configuration setting associated with the shared content may indicate that the second location does not need to be within the predefined distance from the first location.

The server may send the shared content to the second client (step 220). The second client may access, download, or copy the shared content. The second client or the server may open a stream of data referenced by the shared content. The server may send a reference to a location (e.g. a URL) of the shared content. For instance, the shared content may be on a file-sharing service. An application executing on the second client may process the shared content. In some implementations, the second client may communicate to the server or to the first client the receipt of the shared content.

FIG. 2B is another flow diagram depicting a method for sharing content from a first client to a second client. In brief overview, the method 250 generally includes: receiving a shared content and a unique identifier (step 205′); receiving a request from a second client, the request comprising the unique identifier (step 210′); and sending the shared content to the second client (step 220′).

Still referring to FIG. 2B, and in more detail, the method includes receiving a shared content and a unique identifier (step 205′). This step may be similar to step 205 of FIG. 2A. The server may associate the shared content with the unique identifier. A first client may send the shared content and the unique identifier. In some implementations, the first client may have Bluetooth capabilities, and in other implementations, the first client may lack Bluetooth capabilities. The shared content may be associated with an account associated with or logged in on the first client.

The server may receive a request from a second client, the request comprising the unique identifier (step 210′). This step may be similar to step 210 of FIG. 2A. The server may determine that the unique identifier received from the second client is the same as the unique identifier received from the first client. In some implementations, the second client may receive the unique identifier from the first client. For instance, the second client may receive the unique identifier from the first client via a Bluetooth signal, as the second client may be close (e.g., within range of the Bluetooth signal) to the first device. In some implementations, the second client may receive input of the unique identifier from a user of the second client. For instance, the second client may open a dialog or a text input that allows the user to input the unique identifier, which is transmitted to the server. In some implementations, the second client may scan for the unique identifier. For instance, the second client may scan a QR code and decode it for the unique identifier. In another instance, the second client may scan a RFID tag for the unique identifier. The second device may receive the unique identifier from the first device, a user of the first device, a user of the second device, or an input device.

The server may send the shared content to the second client (step 220′). This step may be similar to step 220 of FIG. 2A. If the server may determine that the unique identifier received from the second client is the same as the unique identifier received from the first client, the server may allow the second client to access, download, or copy the shared content. The second client or the server may open a stream of data referenced by the shared content. The server may send a reference to a location (e.g. a URL) of the shared content.

FIG. 3 is a block diagram illustrating an implementation of the server of FIG. 1 in greater detail, shown to include a network interface 305, a processor 310, and memory 315. The network interface 305 may be one or more communication interfaces that includes wired or wireless interfaces (e.g., jacks, antennas, transmitters, receivers, transceivers, wire terminals, Ethernet ports, WiFi transceivers, wireless chipset, air interface etc.) for conducting data communications with local or remote devices or systems via the network 101. For instance, the network interface 305 may allow the server 104 to communicate with one or more first clients 102, one or more second clients 106, other servers 104 and one or more databases. In some implementations, the network interface 305 may have corresponding modules or software that work in conjunction with hardware components. The network interface 305 may receive a shared content, a first location and a unique identifier from the first client 102. The network interface 305 may also receive a predefined distance and other configuration settings from the first client 102. The network interface 305 may receive a request from a second client 106, the request comprising a second location and the unique identifier. The request may be to access, copy, or download the shared content. The network interface 305 may send the shared content to the second client 106. The network interface 305 may send a reference to the shared content to the second client 106. The network interface 305 may send a notification to a second client 106 regarding an availability of a shared content at a second location within a predefined location of a first location. The network interface 305 may send a broadcast to a plurality of second clients 106 that are each associated with a second location determined to be within a predefined location from the first location of the shared content.

The processor 310 may be implemented as a general purpose processor, an application specific integrated circuit (ASIC), one or more field programmable gate arrays (FPGAs), a Central Processing Unit (CPU), a Graphical Processing Unit (GPU), a group of processing components, or other suitable electronic processing components. The processor 310 may be connected directly or indirectly to the memory 315 and the network interface 305. The processor 310 may read, write, delete, or otherwise access data stored in memory 315 or other components. The processor 310 may execute instructions stored in memory 315.

Memory 315 may include one or more devices (e.g., RAM, ROM, flash memory, hard disk storage, etc.) for storing data and/or computer code for completing and/or facilitating the various processes, layers, and modules described in the present disclosure. Memory 502 may include volatile memory or non-volatile memory. Memory 315 may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described in the present disclosure. In some implementations, memory 315 is communicably connected to processor 310 and includes computer code (e.g., data modules stored in memory 315) for executing one or more processes described herein. In brief overview, memory 315 is shown to include a network module 320, content manager 325, and shared content database 360. Memory 315 may further include one or more additional databases such as a clients database 370. In some implementations, one or more databases may be connected to the server 104 via the network interface 305 over a network 101.

Still referring to FIG. 3, memory 315 is shown to include a network module 320. The network module 320 may work in together with the network interface 305 to receive and transmit data via the network 101. The network module 320 may be part of an application, operating system, kernel, driver, runtime environment, and/or other software. The network module 320 may provide one or more applications or modules in memory 315 access to the network 101.

Memory 315 is further shown to include a content manager 325, which comprises an optional API call handler 330, an upload manager 345, a download manager 350, an optional broadcast module 354, and a distance module 358. In some implementations, the upload manager 345 and the download manager 350 may be a single manager or application. The content manager 325 may communicate with or operate under a virtual machine, an operating system, kernel, runtime environment, and/or other software. For instance, the content manager 325 may operate under NODE.JS runtime environment.

The upload manager 345 may receive, from the network module 320, a shared content, a first location and a unique identifier. In some implementations, the upload manager 345 may query a shared content database 360 to determine whether the unique identifier is available. For instance, the shared content database 360 may store a plurality of unique identifiers, and the upload manager 345 may query the shared content database 360 with the unique identifier. The upload manager 345 may associate the received shared content with an account. The upload manager 345 may receive additional configuration settings from the network module 320. The upload manager 345 may notify a first client 102 via the network module 320 that the received unique identifier is unavailable. The upload manager 345 may generate a unique identifier for the shared content. The upload manager 345 may obtain a first location associated with the shared content. For instance, the upload manager 345 may obtain a location associated with an account logged in on the first device from the clients database 370. The upload manager 345 may query the first device for its location to use as the first location. The upload manager 345 may store the shared content in the shared content database 360. The upload manager 345 may communicate with the broadcast module 354 based on configuration settings associated with the shared content. For instance, the configuration settings may specify that the shared content should be broadcasted to one or more devices within a predefined location from the first location.

The content manager 325 may further include a download manager 350. The download manager 350 may receive a request from a second client 106. The request may comprise a unique identifier and a second location. The second location may be a location of the second client 106, a location of an account associated with the second client 106, or a location specified on the second client 106. The download manager 350 may query the second client 106 for the second location. The download manager 350 may query a clients database 370 for a location of the second client 106 or a location associated with an account associated with the second client 106. The download manager 350 may match the unique identifier from the second client 106 with one or more of a plurality of unique identifiers. The plurality of unique identifiers may be stored in the shared content database 360 and/or a database of unique identifiers. The download manager 350 may communicate with the distance module 358 to determine whether a second location is within a predefined location of the first location associated with the shared content. The download manager 350 may compare a password received from the second client 106 with a password associated with the shared content. The download manager 350 may provide the shared content to the second client 106. For instance, the download manager 350 may provide the shared content if the password provided by the second client 106 matches the password associated with the shared content.

The content manager 325 may optionally include a broadcast module 354. The broadcast module 354 may broadcast the availability of the shared content based on a configuration setting associated with the shared content. In some implementations, the broadcast module 354 may be configured by the upload manager 345. For instance, the upload manager 345 may generate or register an event with the broadcast module 354. The broadcast module 354 may execute on a different server. The broadcast module 354 may execute a process or a thread that notifies one or more second clients 106 the availability of the shared content. The broadcast module 354 may notify a second client 106 when the broadcast module 354 detects that the second location of the second client 106 is within a predefined distance from the first location 102. For instance, if a second client 106 enters an area defined by the predefined distance and the first location, the broadcast module 354 may notify the second client 106 the availability of the shared content. In some implementations, the broadcast module 354 may access the clients database 370 to determine one or more locations of one or more second clients 106. In some implementations, the broadcast module 354 may access the clients database 370 to determine an account setting associated with a second client 106 to determine whether to notify the second client 106. The broadcast module 354 may communicate with the distance module 358 to determine whether a second location is within a predefined location of the first location associated with the shared content.

The content manager 325 may further include a distance module 358. The distance module 358 may determine that the second location of the request is within a predefined distance from the first location. The distance module 358 may be called by the download manager 350, the broadcast module 354, or any other application, manager, or module in memory 315. The distance module 358 may obtain the first location stored in the shared content database 360. For instance, the download manager 350 may call the distance module 358 with the first location as a parameter of the call, where the download manager 350 access the shared content database 360 for the shared content and the first location. The distance module 358 may further obtain the predefined distance associated with the shared content. The predefined distance may be stored in the shared content database 360. The predefined distance may be defined in terms of zip code, phone number area code, city, county, state, country, any other geographic designation, or network characteristics.

The content manager 325 may further include an API call handler 330. The API call handler 330 may be connected to the upload manager 345 and the download manager 350. The API call handler 330 may execute one or more API calls made by the first client 102 or the second client 106. The API calls from the first client 102 may be associated or included with the shared content from the first client 102. The API calls from the second client 106 may be from the request from the second client 106. The API call handler 330 may receive one or more parameters for an API call. One of the parameters may be a plug-in identifier. The API call handler 330 may pass one or more parameters to a plug-in module (not shown) such as a chat plug-in.

The memory 315 may include a shared content database 360. The shared content database 360 may be a document-oriented database, a relational database, object model database, a structure query language (SQL) database, a not-only SQL (NoSQL) database, or any other type of database. In some implementations, the shared content database 360 may be a MONGODB. The shared content database 360 may connected to the server 104 via a network 101. The shared content database 360 may receive the shared content from the content manager 325, API call handler 330, upload manager 345. The shared content database 360 may receive a first location, unique identifier, predefined distance, and/or configuration settings. The shared content database 360 may store a plurality of shared contents. The shared contents may be stored with a respective first location, unique identifier, predefined distance, and/or configuration settings. The shared content database 360 may be queried with a unique identifier to determine whether the unique identifier is currently in use. The shared content database 360 may generate a unique identifier that is not currently in use. In some implementations, the shared content database 360 may include a plurality of unique identifiers.

The memory 315 may optionally include a clients database 370. In some implementations, the clients database 370 may be included with the shared content database 360. In some implementations, the clients database 370 may be a document-oriented database, a relational database, object model database, a structure query language (SQL) database, a not-only SQL (NoSQL) database, or any other type of database. The shared content database 360 may connected to the server 104 via a network 101. The clients database 370 may store one or more accounts associated with the first client 102 and the second client 106. The clients database 370 may store locations of the first client 102 and the second client 106. The content manager 325 including the upload manager 345, download manager 350, broadcast module 354, and the distance module 358, may access or modify account settings, first location, or second location from the clients database 370.

FIG. 4 is an illustration of data 400 received from a first client at a server. The server may receive shared content 405 and may optionally receive first location 410, unique identifier 415, predefined distance 420, and/or configuration settings 425. The shared content 405 may include a file, calendar event, document, text, image, animation, video, audio, rich-media, or any other data used by the application. In some implementations, an application or a plug-in executing on the first client may generate the shared content. The first location 410 may be defined in terms of a geolocation, a network location or characteristics, geographic hierarchy location, or any other location. The first location 410 may be obtained from the first client or an account associated with the first client. For instance, the server may receive the first location 410 from the first client or query the first client for the first location 410. The unique identifier 415 may be obtained from the first client or generated by the server. For instance, the server may receive the unique identifier 415 from the first client, generate the unique identifier 415 based on the shared content 405, or randomly generate the unique identifier 415. The unique identifier 415 may comprise a string of characters. For instance, the unique identifier 415 may include alphanumeric, symbols, punctuations, and other characters. The predefined distance 420 may be obtained from the first client. In some implementations, the predefined distance 420 may be set to a default predefined distance. The predefined distance 420 may be defined in terms of geographic distance, geographic hierarchy, network characteristic, or any other distance. In some implementations, configuration settings 425 may include whether the shared content 405 should be broadcasted, password for the shared content 405, additional authorization or authentication, and/or a duration of time during which the shared content 405 will be available. One or more configuration settings 425 may be provided by the first client or set to a default value. The data 400 may be stored in one or more databases, such as the shared content database.

FIG. 5 is an illustrative diagram 500 depicting locations of a plurality of first clients 102 a-b and a plurality of second clients 106 a-c. A first client 102 a may send a shared content to a server (not shown) at a first location of the first client 102 a. The shared content may be associated with a predefined distance that defines a first area 505. The first client 102 a may send a unique identifier associated with the shared content to the plurality of second clients 106 a-c. For instance, the first client 102 a may send the unique identifier to a second server 106 a via ultrasonic sound, to another second server 106 b via Bluetooth, and to yet another second server 106 c via SMS text message. Each of the plurality of second clients 106 a-c may send a request to the server with the unique identifier and a respective second location. For instance, a second client 106 a may send a request to the server with its own location as the second location and the unique identifier received from the first client 102 a. In response to each request, the server may determine whether the second client making the request is within the area 505, e.g. whether the second location is within a predefined distance from the first location. In response to the request from second clients 106 a and 106 b, the server may determine that the two second clients 106-b are within the area 505 and send the shard content to the second clients 106 a-b. The server may also determine that one of the second clients 106 c is outside the area 505 and notify that second client 106 c that the shared content from the first client 102 a is not available at the present location of the second client. In some implementations, the second client 106 c may later move within the area 505 and request the server for the shared content, at which point the server may send the shared content to the second client 106 c.

Another first client 102 b may upload another shared content from a first location. The first client 102 b may also provide a predefined distance that defines a smaller area 510 than the area 505 defined by the predefined distance associated with the other first client 102 a. The first client 102 b may provide a unique identifier, password, and a broadcast setting that specifies that server will notify second clients 106 b-c that are within the smaller area 510 of a shared content from the first client 102 b.The server may not notify a second client 106 a that is outside the smaller area 510. However, if the second client 106 a later moves within the smaller area 510, the server may notify the second client 106 a of the availability of the shared content from the first client 102 b.
